In a serious blow to one of the cornerstones of a united, integrated Europe, EU interior ministers embarked on a radical revision of the passport-free travel regime known as the Schengen system to allow the 26 participating governments to restore border controls.

They also agreed to combat immigration by pressing for “readmission accords” with countries in the Middle East and north Africa to send refugees back to where they came from.

The policy shift was pushed by France and Italy, who have been feuding and panicking in recent weeks over a small influx of refugees from Tunisia. But 15 of the 22 EU states which had signed up to Schengen supported the move, with only four resisting, according to officials and diplomats present.
